It's recently been reported that investing in Lego is actually more lucrative than investing in Gold. The popularity of the interlocking brick based system has increased dramatically in recent years and that must be good news for the Legoland Resort in Windsor. If you've never been then a trip to Costa Bingo could prove to be a wise investment!

Costa Bingo latest promotion is called Build A Break and it gives you the chance to win a £500 Legoland Annual Entry for two adults, two children and two seniors plus a £500 cash prize. If you're not a fan of Lego then you can substitute the pass for another £500 cash.

Tickets for this game are a whopping £5 each which isn't particularly attractive. However as usual Costa Bingo are offering you the opportunity to pick up free cards. Unfortunately we don't think this is their best freebie offer. You can claim one free card for every £100 wagered on slots between the 15th and 21st January!

When you consider that the vast majority of bingo brands are advocating bargain games and January sales this month, a £100 wager on slots for one free ticket is not that attractive. Remember though that the wager amount doesn't always mean depositing amount. If you deposit £10 and use that to win £20 on slots - then play that £20 - you've wagered £30 in total. That said we still find the £100 amount for a free card a little too expensive a qualifier.

The good news though is that you can collect free tickets by using Diamonds - you get one for 10 Diamonds. In our view that's the best way to get involved with this game. As you collect one Diamond for every £1 wagered on Costa Bingo, it's possibly better value to play £10 on bingo. That gets you the 10 Diamonds and therefore the free ticket.

By the way when visiting Costa Bingo this month you'll notice that once again Mel B has left the building - again. The Spice Girl and now Lip Sync UK judge's presence has gone and we suspect that this time she won't be back. It was a surprise to see her return last year but Costa really didn't make as much use of Mel's endorsement as they had done when they first added her to the site.

We do wonder whether Costa Bingo will bring in another big name this year?
